Simple improvised guitar on cheap acoustic, except 120110_23 which is electric but not plugged in. Recorded with a Sony M-10 and processed with Amplitude and some other things that I can't remember.

Edit: I just listened to the original recordings. These were played on an unplugged electric. Mostly simple repetitive notes using a plectrum. The originals have been stretched in Cool Edit before applying the software amp effect. The time stretching process giving the notes sustain rather than delays from the amplifier.
